I just found this on the global site of LG Electronics (http://www.lge.com/general/lg_globalsite.jsp). This map links to the separate LG country sites, sorted by regions. Call me a total nerd, but check this out:
Instead of a reunified Germany, I'm seeing a thick border still running between former East Germany and West Germany (I grew up in East Germany, and I can testify that the reunification did happen.....17 years ago); instead of the Czech Republic and Slovakia, I still see the former Czechoslovakia (which ceased to exist more than 14 years ago...); the CIS is not a nation, it's a commonwealth of sovereign states - the LG map shows the former Soviet Union including the three Baltic states (that never belonged to the CIS but are members of the European Union) and Turkmenistan (which withdrew from the Commonwealth of Independent States in 2005). And: Since there's no separate LG country site for Iceland, I'm not going to mention that Iceland actually belongs to Europe and not to North America (Iceland gets tinted, too, when you roll over North America).
It appears that LG doesn't seem to acknowledge the global political situation after 1990. Sweet, sweet Cold War.
I actually kinda like these little bugs on the map if they just weren't of such a scandalous shame for a global company like LG. Nonetheless I tried to send them a mail thru their "Contact Us" mail form to suggest a slight revise of this map (hint, hint!), but their mail form was so badly coded that - after trying three times - I wasn't able to deliver the message to LG.
So let's just leave LG as the Sleeping Beauty and enjoy the good ol' times before the events of 1989.
A little programmer carriage for an 8-pin ATTiny chip. It's basically just an ISP header and a DIP socket.
They arrived today from Russia!
All twelve are in great condition considering that they were made in mid 1980 - they were packaged very well, foam covering some kind of milk-thing-box from Russia which contained more foam wrapping the actual tubes. The tubes are 2 inches high from bottom of the glass to the top, and the characters are 2cm high. Tubes from tubes-store.com/ who still have loads of this type (IN-14) left.
Once I've got some free time I'll turn these into a clock, but first I have to figure out how to generate 170V DC...
The city of Chicago's electronics recycling facility on Goose Island operates like a drive-thru. The large group of people working there were weirded out when I showed up on my bike with my busted flat-screen monitor. 1105 N Branch Street, open Tuesday 7a-2p and Thursday 2p-7p.
Design and build an odometer and speedometer for a model railroad. The distance/speed measuring instrument shall be installed in a separate model railroad car (with its own battery for a power source) and shall display the total distance the train has traveled (in scale miles) and the speed of the train (in scale miles-per-hour). The odometer shall display values from 0.0 to 9.9 scale miles and the speedometer shall display 00 to 99 scale miles-per-hour. The speed display shall be updated about once a second. The measurement shall be accurate to ±1%.
The wheel on the railroad car has a diameter of 33.6 scale inches. A transducer is mounted on the axle that produces four “square” pulses per revolution of the wheel.
We came across an interesting oddity from the realm of consumer electronics: a fake seven-segment LED display. Just for fun, we made our own version too.

My lifelong quest to get electrocuted continues.
This is an electronics proof of concept for a table lamp that I want to make, it's called "North" and is brighter the closer it is pointing to north.
I was also, rather self-centeredly, thinking about making one that burns brighter the closer it is pointing to the place where I was born, a hospital in Stockholm, although the idea would be that a person would choose a place that means something to them personally, whatever it is.
I'll have to get a little GPS module chip and see if it could work.
Usability wise where the lamps needs to point doesn't really matter as all you would be looking for is to get the right level of light.
I went for the danger option and added one more nixie, bringing it up to four. Of course I had to have them display 1337.
Looking inside the metal box you can see the deep cycle battery, charge controller, power supply, and the computer with the custom circuit to turn on/off the computer when the sun is out. On the right is the La Crosse weather station.

Getting ready to build a keyboard with 7 segment LED display and interface for the SC126, a Z180 based computer.
Here's a Joule Thief standing on a metallic/conductive surface which allows the circuit to close and the LED lights. The magnets at the ends of the armature are neodymium.
The Electronics still require a lot of work before they're complete, it's definitely keeping my Dad busy. While he's been working on the code and hardware, I fitted all the components I could; IR receiver, proper cabling and one out of two speakers. It doesn't sound too shabby at the moment, and it's only going to get better.....
Did you know that hemostats are excellent for holding small electronic components. I rely on them most when desoldering as they can lock on to a component saving my fingers from having to have direct contact. They can also be useful when placing certain components. This is a old trick I learned from my friend Jesse when I lived in NYC. I've never seen anyone else use them, but they are great.
What to do if you favourite microcontroller doesn't have enough hardware PWM pins? Software driven PWM of course.
There many absolutely dumb ways to do it, and I've probably tested all of these. They can be classified as "brute force".
A better way of doing it is to only do any work if there is anything to do. But you already know all of this of course. Calculate when to toggle the lines and let a timer do all of the work. Code can be found on my blog
The car is heavy on its springs as I bring a load of old computers to the local electronics recycling day. The total was 2 monitors, 2 printers, and 2 external HD arrays and about 12 computers of various vintages back to a 486.
There was absolutely no service at the ranch before Wilson Electronics. The Wilson Electronics Sleek provides service in the Jeep while in the pasture. This was without the Sleek.
Portable audio player built with an Arduino Duemilanove, and Adafruit Waveshield, mylar speaker, 9v battery.
